Hurricane Earl and the low pressure area that now has a 90% chance of becoming Tropical Depression 8 moving west through the central Atlantic. The low pressure area’s showers and thunderstorms are gradually becoming better organized in association with a low pressure system located about 1050 miles east of the Lesser Antilles. Right now the National Hurricane Center gives the low a high chance of becoming tropical depression 8 in the next 48 hours. That may mean a one-two punch for the Leeward Islands. The low is moving west at about 20 mph. |

Hurricane Danielle became the first major hurricane of the 2010 Atlantic hurricane season overnight as it continued to make its way through the central Atlantic. Danielle, which had been a Category 2 storm the day before with sustained winds estimated at around 95 knots (~110 mph) by the National Hurricane Center, quickly intensified overnight and by morning was a power Category 4 hurricane on the Saffir-Simpson scale with sustained winds of 115 knots (132 mph). “The TRMM satellite passed directly over Danielle during the night and captured remarkable images as the storm was in the process of intensifying,” said Steve Lang, research meteorologist on the TRMM team in the Mesoscale Atmospheric Processes Branch at NASA’s Goddard Space Flight Center in Greenbelt, Md. Two images were taken from TRMM at 06:46 UTC (2:46 a.m. EDT) on August 27. The first image showed a top-down view of the horizontal pattern of rain intensity within the storm. Rain rates in the center of the swath are from the TRMM Precipitation Radar (PR), and those in the outer swath are from the TRMM Microwave Imager (TMI).The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS), and are created at NASA Goddard. TRMM is managed by both NASA and the Japanese Space Agency, JAXA. |
